Hello, we also have interest in Media Source support for the GStreamer backend, although using the QtWebKit port. I've added to the CC list, including Philippe Normand (philn) as discussed in the channel #webkitgtk+. Hello Philippe, since I found this existing new bug, I just commented on it, rather than open another. Thanks and regards Nadia, any news to share about this bug? Created attachment 195677 [details]
Media Source Player for the GStreamer Backend (prototype architecture)
Hi Philippe,
I'm sorry for not following up earlier. The reason is that we did start implementing a Media Source player prototype for the GStreamer backend, but had to put it on hold indefinitely as we changed to a proprietary solution that is still in progress. Unfortunately, a proposal for the GStreamer Media Source implementation had not yet been prepared.
To summarize the work done, our prototype was implemented in QtWebKit1 (Qt 4.8) and was based on the Media Source specification version 0.5. We referenced the Chromium implementation to help us understand how Media Source should work.
We know there have been many updates to the spec and to WebKit since then, including the recently added MediaSourcePrivate interface. In general though, our approach was the following (please also see attached for a diagram of the implemented architecture) :
* The existing MediaPlayerPrivateGStreamer engine was modified to support Media Source URIs, in addition to the existing support for web (http/https) URIs.
* Similar to the existing WebKitWebSrc gstreamer element that handles web URIs, a new gstreamer element named WebKitMediaSourceSrc was implemented to handle Media Source URIs.
* WebKitMediaSourceSrc registers its URI protocol handler, allowing uridecodebin to dynamically create the appropriate source element, either WebKitMediaSourceSrc or WebKitWebSrc, based on the provided URI.
* A new class MediaSourceGStreamer was also added to encapsulate the Media Source API implementation. If a Media Source URI is loaded, MediaPlayerPrivateGStreamer creates a MediaSourceGStreamer object, to which it forwards Media Source API calls.
* Similar to the existing WebKitWebSrc element that uses a StreamingClient object to interface with WebKit's network layer and receive media data, the WebKitMediaSourceSrc element uses a new MediaSourceClientGStreamer object to interface with MediaSourceGStreamer and receive media segments.
* The WebKitMediaSourceSrc element has “sometimes” source pads and creates one appsrc per Source Buffer, when the Media Source API function sourceAddId() is called.
* The GStreamer Source Buffer model was not fully analyzed. For the prototype, a Source Buffer was simply implemented as a struct named WebKitSourceBuffer that is associated with an appsrc.
With this approach, we were able to play simple Media Source examples that append one or many non-overlapping media segments, but we did not finish implementing the full API, nor operations such as pause, seek or getting the buffered time ranges.
Unfortunately, this is all the news we have available at this time. We were not able to prepare a proper proposal for sharing before changing our approach.
Thanks and best regards.
Thanks Nadia, the work you folks did seems quite reasonable and interesting! Have you considered upstreaming your current prototype? I believe there is some interest in the community to continue the work, if it can be based on the prototype it would be awesome. Hi Philippe, Glad to hear your feedback about the work done, thanks! Yes, Bluestreak can release the prototype to the community. By upstreaming, does this mean submitting a patch and going through the code review process, even though the current functionality is incomplete, the software model is not finalized and the existing Media Source layout tests would fail? The prototype code would also need to be integrated into the latest WebKit and GStreamer 1.0 ( we used GStreamer 0.10). As well, I had not yet taken a good look at the Media Source layout tests; but since they already exist, I suppose it would not be required to add more tests with the patch? Apart from the webpage http://www.webkit.org/coding/contributing.html, would you have additional guidelines to follow for contributing code? Thanks and best regards. At this point I would focus on gst 1.0 support only, if possible. The contributor guidelines should provide you a good enough procedure for the patch submission. If the patch can unskip at least some mediasource layout tests, the better. No need to write new tests. Ok. I'll take a look at gst 1.0. I had a discussion with Nadia to confirm my interest on working on this bug. We have a project which consists on developping an adaptative streaming application (MPEG-DASH) using the QtWebkit port. I have not a relevant experience on WebKit and before I start working on it, I want to be sure of architecture solution that will be implemented. Could someone confirm that Nadia's solution is a good starting point: - Create a MediaSourceGStreamer object - Create a new gstreamer element: WebKitMediaSourceSrc Thanks and best regards (In reply to comment #8) > I had a discussion with Nadia to confirm my interest on working on this bug. > We have a project which consists on developping an adaptative streaming application (MPEG-DASH) using the QtWebkit port. > I have not a relevant experience on WebKit and before I start working on it, I want to be sure of architecture solution that will be implemented. > > Could someone confirm that Nadia's solution is a good starting point: > - Create a MediaSourceGStreamer object > - Create a new gstreamer element: WebKitMediaSourceSrc > > Thanks and best regards Yes that would be a good approach I think.

(In reply to comment #16) > To respect architecture, i need to multiplex an Audio stream and a video stream with playbin but playbin only support one appsrc. do you have any idea ? It might be a good timing to consider writing your own element. It would be more flexible then appsrc I think. Or you could output a multiplexed stream with both audio/video from appsrc, and then have your custom demuxer to split it again later.

> + KURL url(KURL(), uri);
I wonder if this shouldn't be:
KURL url(KURL(), uri + 5);
because else the url.protocolIsInHTTPFamily() call will fail. At least on my setup it does.
I have tested this on QT4.8 with qtwebkit 2.3.2 (I have patched up the media source api from webkit), gstreamer 0.10.36 and I was wondering about the following:
When testing with youtube.com/tv the load() function is called twice, with two different blob urls. Is this normal?
Also how does one find the url for the audio? I'm just beginning to read about the Media Source Extensions and I haven't understood it all yet.
Also what version of the API is used currently in webkit, since it's changing by the day? The current last revision is July 26th.
I'm also interested in this, but I've just begun to study the problem.

You are right, I forgot to remove the test with "url.protocolIsInHTTPFamily" when GST_API_VERSION_1 is undefined. > I have tested this on QT4.8 with qtwebkit 2.3.2 (I have patched up the media source api from webkit), gstreamer 0.10.36 and I was wondering about the following: > When testing with youtube.com/tv the load() function is called twice, with two different blob urls.

Patch
r- as per review comments. Looking forward the next iteration!
Just a heads up: I'm working on merging in changes in MediaSource from Blink in bug #118752, which may break this patch, as some of the class structure of MediaSource objects will change. The breakage should be minimal and easily fixed however. Here is a status of my progress. I had worked on a custom demuxer solution: I had a specific header on audio and video buffers in appsrc. The demux detetects headers and redirects buffers on audio or video pad. I am having troubles with following demuxer (qtdemux,..) although i set the offset and renegociated caps. There is no problem if the stream is only composed of video buffers or audio buffers. i am stuck on this problem. I have tried another solution: Create a bin with 2 appsrc. Uridecodebin manages sources with multiple pads if they are dynamics. This solution works on a test application. When i integrate it in Webkit and test with the website http://dashif.org/reference/players/javascript/0.2.5/index.html, the delay to feed first video and next audio seams to cause problems.

The new delivery takes into account the various comments. Regarding the comment: > Source/WebCore/platform/graphics/gstreamer/MediaSourceGStreamer.cpp:56 > +MediaSourceGStreamer::AddStatus MediaSourceGStreamer::addSourceBuffer(const String& type, const CodecsArray& codecsArray, OwnPtr<SourceBufferPrivate>* sourceBufferPrivate) Wow, an OwnPtr<>* ? First time I see that. I have taken what is already done in the source code file "MediaSourcePrivateImpl.cpp" in Chromium As said earlier, I deliver a solution with a bin including 2 appsrc. However, this solution works with a test application but returns systematically "streaming task paused, reason not-linked (-1)" in webkit. As a consequence i have deactivated audio in this delivery (AUDIO_APPSRC not set) Does someone have a solution to progress For your information, I realized my tests with gstreamer-1.0.6 on the website http://dashif.org/reference/players/javascript/0.2.5/index.html Created attachment 211784 [details]

- Please fix as much style errors as possible - Provide documentation and an explanation of the patch in the changelog - media-source needs to be enabled by default in build-webkit --gtk - about the blob uri scheme, I think the element should handle a different scheme (mediasource:// ?) and the player should transparently transform the scheme when loading the resource (see how it is done in bug 108088) - I'm not sure a bin is the best approach for an element with sometimes-pads, have you checked how other elements are implemented?

We have a bajillion skipped tests marked against this bug. Reopening. Please either move the tests to a different bug, or else unskip them before closing this one. I'm also confused why we are skipping all of imported/w3c/web-platform-tests/media-source/, but only a few selected tests under media/media-source/. Skipping also test media/media-source/media-source-seek-detach-crash.html which has been timing out since r207621 (In reply to comment #69) > We have a bajillion skipped tests marked against this bug.
